Specification of Letters Patent.

Patented Nov. 11,1913.

Application filed June 15, 1912. Serial No. 703,783.

To all whom it may concern:

Be it known that I, HARRY Lnnnsrnonn, a citizen of the United States, residing at Poplar Bluff, in the county of Butler and State of Missouri, have invented new and useful Improvements in Adding and Recording Machines, of which the following is a specification enabling those skilled in the art to which my invention appertains to understand the same.

This invention relates to adding machines in which there is a main shaft, which shaft in a sense performs the functions of an operating shaft, in that the operation of the shaft enables, or causes, or permits the machine and the combined mechanisms thereof .to perform their respective and combined functions and duties. This shaft may be re .ferred to also as a rock shaft, since it is usually operated in rocking movements.

An object of the invention is to provide an improved combination of elements for operating the shaft.

Another object is to provide an improved connection between an operating handle and the shaft.

A further object is to provide a novel and improved means for holding the shaft and handle in connection with each other whereby the handle is operative effectively to rock the shaft in one direct-ion but is releasable from the shaft when moved in the opposite direction.

An additional object is to provide a novel combination of operating elements co iprising a support in the form of a bushing or hub for the shaft, engaging elements on the shaft and on the bushing or hub, respectively, whereby a rocking movement of the bushing or hub will rock the shaft in one bushing or hub free to r turn independently and in advance of L118 shaft, and a handle provided with improved means of connect-ion with the bushing or hub for rocking the said bushing or hub as aforesaid.

Other objects and advantages to be derived from my invention will be apparent to those skilled in the art to which the invention relates Without specific mention thereof.

' Said objects and advantages will appear from the following description, reference be ing made to the accompanying drawings in which I have shown one embodiment of my bushing 5 invention in combination with a well known adding machine, and in which Figure 1 is a side elevation of a Dalton adding machine illustrating the handle and a part of the connections whereby the handle may rock the main operating rock shaft of the machine. Fig. 2 is a plan view of the combination of elements constituting the subject-matter of my present invention. Fig. 3 is a view partially in section on a line 3-3 of Fig. 2.

lVhile I have shown my invention em- ASSIGNOR TO DALTON ADDING bodied in and combined with a Dalton adding machine, it will be apparent that it is equally as well applicable to any adding machine employing a main operating rock shaft. 1 do notv restrict my inventlon to any particular or specific type of adding machine.

The Dalton adding machine is manufactured within the scope of Hopkins Patent No. 1,039,130, dated September 24, 1913, and is a substantial embodiment of the adding and listing mechanism in said patent.

Vithin the machine there is a shaft 1, which has heretofore been referred to as the main operating rock shaft of the machine. The shaft 1 is mounted in a substantially horizontal position in the machine and its operation is necessary in order to permit the machine. and the various combined mechanisms thereof, to perform their several and joint functions. The shaft 1 is a rock shaft and is arranged to be rocked in one direction by one element and in the other direction to its idle or initial position by a spring 2, having one end connected to an arm 3 on the shaft, and the other end in connection with some stationary part of the machine.

- Near one end of the shaft 1, which is adjacent to one side of the machine, is a fixed bearing 4 in which is revolublv mounted a -mcmfoer 5 which constitutes a hub or bushing inwhich the end of the shaft 1 is supported; as illustrated in Fig. 8. The hub or is held from outward movement by a flange 6 near its inner end. which engages against the bearing 4. The shaft 1 has an arm or plate 7 attached thereon and the hub or bushing 5 has an arm or lever 8 rigidly secured to its inner end close to the arm or plate 7. The said arm or plate 7 has a projection 9 on its outer side above and in the path of movement of the arm or lever 55, so that when the hub 0r bushing wsrcl inovcn'ieiit she" is limitecl snci idinei h l1 D or busiiito we or bushing o is provided wiuli a tapeing; extension ll which projects into 01. through on opening" in the ease of the ma.- chine to permit connection of the lmmlie therewith while the case is in position. A pin 12 is rigid with the extension 11'. The operating; handle or lever 13 is formed in te 'ral or rigicl with a limb socket is in win .n there is a towering bearing; or opening arranged to receive the QFZ'EQnSiOZl 11 shown. The soi hub or socket 1 1' lies 9. slot 15 extending: obliquely inwardly from the of the hub or socket and arranged so receive iilie pin 12 when the handle is mouniied in opersiive position. The parts are or rsngerl with respect to each other so that when coniiec iei, the handle will be supporiierl sobsisnivislly in. the position in 1. drawn forwardly in loos when the clireefiion of snow 16 the she will no rocked in opposition to sp and ti o various mechanisms will be 0 a steel to perform their oiunies and functions. Forwa d movement of the hanclle and is limited by a suitable stop 17 against which the arm or piste 7 engages.

It will be noieci 'thsi; she lisnoile is l laeeti in connection Wi the shaft by placing the socket or he}; l i over he end of 'tlie extension 11 so that the pin 1 H l2 will be received Within the open end of the slot 15; the hondie is then drown forwardly a short distance and the pin 12 clrews *zhe hub or socket 14 onto extension 11 and frictionolly bimls or ioclzs the iogether. After the handle films been mounieci, forward moveroene thereof rocks the shaft 1 by a oosiiblre action out rearward movement nclependon; of the shaft, when the shaft is forward, permitted either by movementof the hub or bushing 5 at a speed greater than one return movement of Joe shaft 1', or by the releasable connection between the henrlle and the litfillSlOll 11. Tile l .il'fllQ maybe remove'cl oisny time by movement in the direction of the arrow 18,

remorse which movement will cause the pin in Lu release tie hub or socket from its frictionoi engagement with said extension 11.

I do not resrici myself to the specific 21rrangemeni; of the parts, but

8. In an adding machine, the combination With a main operating rock shaft and the springs for rocking said shaft in one direction and holding said shaft in idle position, of an armon said shaft, a hub loosely mounted on said shaft, an element rigid on said hub engaging with said arm, a pin on sa d hub, a handle, a socket on said handle arranged to receive said hub and having a slot to receive said pin, and abutments limiting movement of said shaft, substantially as specified.
